Abstract

A multifunctional safety warning device for a vehicle includes a mediate light bar zone having a first side and a second side; a left indicating light mounted on the first side of the mediate light bar zone and being adapted to light independently; and a right indicating light mounted on the second side of the mediate light bar zone and being adapted to light independently. In such a manner, the mediate light bar zone, the left indicating light, and the right indicating light are connected to and controlled by a control unit, whereby, the control unit is used to alternatively operate the mediate light bar zone, the left indicating light, and the right indicating light of the safety warning device, and to operate a set of breakdown light of the vehicle so that at least one set of light is used indicate a steering direction of the vehicle.

Claims

1. A multifunctional safety warning device for a vehicle comprising:

a mediate light bar zone (10) having a first side and a second side;

a left indicating light (30) mounted on said first side of said mediate light bar zone (10) and being adapted to light independently; and

a right indicating light (20) mounted on said second side of said mediate light bar zone (10) and being adapted to light independently;

wherein, said mediate light bar zone (10), said left indicating light (30), and said right indicating light (20) are connected to and controlled by a control unit (16), whereby, said control unit (16) is used to alternatively operate said mediate light bar zone (10), said left indicating light (30), and said right indicating light (20) of said safety warning device (1), and to operate a set of breakdown light of said vehicle so that at least one set of light is used indicate a steering direction of said vehicle.

2. The multifunctional safety warning device in accordance with claim 1, wherein when said breakdown light of said vehicle blinks, said control unit (16) is used to operate said left indicating light (30) and said right indicating light (20) of said safety warning device (1) so that said left indicating light (30) and said right indicating light (20) do not blink so as to indicate a turn left/right steering direction of said vehicle.

3. The multifunctional safety warning device in accordance with claim 1, wherein when said left indicating light (30) and said right indicating light (20) of said safety warning device (1) blink, said control unit (16) is used to operate said breakdown light of said vehicle so that breakdown light of said vehicle does not blink so as to indicate a turn left/right steering direction of said vehicle.

4. The multifunctional safety warning device in accordance with claim 1, wherein when said left indicating light (30) and said right indicating light (20) of said safety warning device (1) blink, said control unit (16) is used to operate said mediate light bar zone (10) so that said mediate light bar zone (10) lights continuously, thereby facilitating a following vehicle apparently distinguishing said left indicating light (30) and said right indicating light (20) and knows a front vehicle is disposed at an emergency state.

5. The multifunctional safety warning device in accordance with claim 1, wherein a light source of said safety warning device (1) is an L.E.D.

6. The multifunctional safety warning device in accordance with claim 1, wherein a light source of said safety warning device (1) is a bulb.

7. The multifunctional safety warning device in accordance with claim 1, wherein said control unit (16) is a central processing unit (C.P.U.).

8. The multifunctional safety warning device in accordance with claim 1, wherein said control unit (16) is an equivalent control circuit.
